In recent years, they’ve managed to get Lake Ponchartrain cleaned up enough that you could actually swim in it again. Now it looks like the lake is going to take a huge hit of pollutants as the Orleans and Jefferson Parishes are dried out:
Earlier this year, scientists found as many as 20 manatee had taken up residence in the lake, apparent visitors from the Florida coast. Dufrechou said he hopes they will be able to avoid the dirty water as it’s being pumped into the lake. But the water will definitely be bad news for rangia clams that have repopulated the south shore of the lake during the past 10 years.
